Oil Temp gauge installed

So I've had the gauge in for about 6 months and lots of towing. 

 

In the summer on a 100° day, pulling a long grade the oil will get up to 235° when the coolant is 209-210°, that's at anywhere from 17-23K GCW

 

Last week I ran 750 miles in one day to Wyoming and back and never saw the oil get above 205°, and I was towing the whole way. I was towing about 8.5K lbs out to Wyoming and 4K back. 

 

On the way out the ambient temp was 12-23° and coolant held 193-195° at 75 on the interstate and oil was 195-197°, on the way back I ran 80 on the interstate an oil temps crept up to 205° on some hills, but the ambient was up to 35-43°.

 

All in all, it has been a fun gauge to watch and ambient temp does play a big role in how fast it warms up, cools down, or how hot it will hold when towing.
